Artists must learn, if they do not know, how to control their own affairs, and if they are determined to succeed, they must not think of trusting their interests to the keeping of those not of their profession, and entirely uneducated in art, and who consequently cannot be qualified to discharge so delicate a duty with judgment and fidelity. It is an old saying, but very applicable to the present instance, that "if you neglect your own business, you need not expect others to attend to it for you." Let artists depend more upon private sales of their works to those who can appreciate them for a just remuneration, than upon the deceptive offers which chartered schemes may hold out to them. They will then, by their worth and their artistic merits, build up about them a solid body of friends and patrons, of whom nothing but death itself can rob them; and the number of whom time will but increase, until they may look forward with well-founded hopes to a peaceful and honorable old age, and a full reward for all their labors. They cannot justly suppose that permanent success and a distinguished name can be attained through any other channel than by honesty, and excellence in their works. Honors and rewards from private sources may be very laggard in their approach, but they must ultimately come--especially in this enlightened, progressive, and prosperous country--to those who have fairly earned them. Recent Deaths. Those who have been accustomed to visit the bookstore of Bartlett & Welford, under the Astor House, during the last half-dozen years, must have been familiar with the commanding figure and gentle but uneasy expression of our late excellent friend, the Rev. SERENO E. DWIGHT, D. D., who died in Philadelphia on the thirtieth of November, in the sixty-fourth year of his age. Dr. Dwight was born in Greenfield, Connecticut, in 1786, and was educated at Yale College, where he was graduated in 1803, being then about seventeen years of age. He became a tutor in the college, but soon abandoned this occupation to commence the study of the law at Burlington in Vermont, and in a few years he was admitted to practice in the highest courts of the country. An early and ever-increasing predilection, however, led him to the profession of his father, and upon completing his theological studies he was settled over the Park-street Congregational church, in Boston, where, he rapidly acquired the fame of being one of the ablest, most eloquent, and most useful divines in New-England.
